How to make ActionBar and stacked bar share same background image

is it possible for actionbar and it's stacked bar(one that contain navigation tabs) to share same background image? one that starts from actionbar and ends at stacked bar?

currently the way am implementing this, am ending up having action bar with it own image and stacked bar with its own.

my styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:actionBarStyle">@style/MyActionBar</item>
<item name="android:actionMenuTextColor">@color/app_yellow</item>
<item name="android:windowActionBarOverlay">true</item>

<!-- Support library compatibility -->
<item name="actionBarStyle">@style/MyActionBar</item>
<item name="actionMenuTextColor">@color/app_yellow</item>
</style>

<!-- ActionBar styles -->
<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">

<item name="android:titleTextStyle">@style/MyActionBarTitleText</item>

<item name="android:actionBarTabTextStyle">@style/MyActionBarTabText</item>

<item name ="android:actionBarTabStyle">@style/MyTabStyle</item>

<item name="background">@drawable/actionbar</item>

</style>

<!-- individual ActionBar tabs style -->
<style name="MyTabStyle" parent ="Widget.AppCompat.Light.ActionBar.TabView">
<item name ="background">@android:color/transparent</item>
<item name ="android:background">@android:color/transparent</item>

</style>


in my activity

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ActionBar actionBar = getSupportActionBar();
// Specify that tabs should be displayed in the action bar.
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setLogo(R.mipmap.ic_launcher);
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setDisplayShowHomeEnabled(true);
actionBar.setStackedBackgroundDrawable(getResources().getDrawable(R.drawable.actionbar));

Answer

From Michael De Soto guidance(see his comment above), i was able to have actionbar and stacked bar share same background image by using a toolbar that has

  • actionbar details(e.g icons,titles) in views(textview for titles, imageviews for icons etc)

  • Stacked bar details(basically tabs) in a tablayout.

my output Here how i implemented it guys

my activity xml

<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:id="@+id/mainActivityBar"
    android:layout_alignParentTop="true"
    android:background="@drawable/actionbar"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetEnd="0dp"
    app:contentInsetRight="0dp"
  >
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="President"
            android:id="@+id/appname_1"
            android:background="@android:color/transparent"
            android:textColor="#ffffff"
            android:layout_marginLeft="20dp" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            style="@style/myCustomTabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:layout_below="@+id/appname_1"
            android:layout_alignParentEnd="true"
            android:layout_alignParentStart="false"
            android:layout_alignParentLeft="false"
            android:layout_alignParentRight="true"
            android:layout_alignParentBottom="false"
            android:layout_alignLeft="@+id/appname_1"
            app:tabGravity="fill"
            app:tabMode="scrollable"/>
    </RelativeLayout>

</android.support.v7.widget.Toolbar>

added the following in my styles.xml

<style name="mainActivityTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <!--We will be using the toolbar so no need to show ActionBar-->
    <item name="android:windowActionBar">false</item>

</style>

<style name="myCustomTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabIndicatorColor">?attr/colorAccent</item>
    <item name="tabIndicatorHeight">2dp</item>
    <item name="tabSelectedTextColor">?android:textColorPrimary</item>
</style>

Finally, my activity

public class MainActivity extends AppCompatActivity {

private SectionsPagerAdapter mSectionsPagerAdapter;

TabLayout tabLayout;

private ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    Toolbar toolbar =(Toolbar) findViewById(R.id.mainActivityBar);
     setSupportActionBar(toolbar);

    tabLayout = (TabLayout) findViewById(R.id.tabs);

    // Create the adapter that will return a fragment for each of the three
    // primary sections of the activity.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    // Set up the ViewPager with the sections adapter.
     mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);
    mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    tabLayout.setupWithViewPager(mViewPager);
}

public class SectionsPagerAdapter extends FragmentStatePagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        switch (position) {
            case 0:
              return Item1fragment.newInstance();
            case 1:

                return Item2fragment.newInstance();
            case 2:
                return Item3fragment.newInstance();

        }
        return null;
    }

    @Override
    public int getCount() {
        // Show 3 total pages.
        return 3;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
            case 0:
                return "Item1;
            case 1:
              return "Item2";
            case 2:
               return "Item3";
        }
        return "";
    }
 }

}

GOOD LUCK! everyone!
